About our air conditioning servicing in Cobham
For an annual service, the price is £95–£150 + VAT, confirmed before the visit is booked. Multi-split, ducted and commercial systems are priced once we know what’s there. There’s no guessing at the bill afterwards. We’re often asked to deal with new noises from the indoor or outdoor unit and F-gas leak checks falling due, on wall-mounted split systems, air-to-air heat pumps and multi-split systems.
We book services in Cobham at a time that suits you, and a single system usually takes an hour or two.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

How the job changes from property to property
Filters
Certain indoor units carry additional filters alongside the main ones. They’re checked too, and we explain what the manufacturer suggests.
Indoor and outdoor coils
Room air passes over the indoor coil, which takes heat out or puts it in. We clean it so air can pass through the fins and heat can pass in and out, and we look for damage or corrosion.
Questions from Cobham
Does my air con in Cobham need a yearly service?
A yearly visit is right for most households. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Do you cover smaller places like Cobham?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Does my air conditioning need an F-gas leak check?
The requirement starts at 5 tCO2e. Many small split systems fall below it: 3 kg of R32, for instance, is about 2.0 tCO2e. We read the charge from the label and work it out for you.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll tell you what to do first.
What accreditations do you have?
We’re an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are also Checkatrade members.
What does F-Gas certified mean?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.

What happens on the day

It takes an hour or so for a single wall-mounted unit, longer for a multi-split system, and we clear up before we go. Photos of the existing unit and its label help with repairs and servicing near Cobham.
- It begins with a few questions about the make, the rooms served and any symptoms.

Leave it or put it right?
